Опубликовано: 3 Января, 2023

jQWidgets — это JavaScript-фреймворк для создания веб-приложений для ПК и мобильных устройств. Это очень мощная, оптимизированная, независимая от платформы и широко поддерживаемая платформа. jqxDataTable используется для чтения и отображения данных из таблицы HTML. Это также используется для отображения данных из различных источников данных, таких как XML, JSON, Array, CSV или TSV.
